The end result hopefully without halos/glow should look like this: To correct these cases, switch to the Erase Overlay Tool set the hardness to 0% (you may also want to reduce the brush size a little) and from the other side of the boundary (the one you are NOT selecting) paint again near the edges without letting the cross in the centre touch the boundaries to smooth out the thick edges a little - the goal here is ensure that they are neither too thick/dark nor entirely deselected/affected (leaving a white outline around the edge) - the more neutral they look (no darker nor lighter outline around the edge) the better. While passing a few times with the brush it's possible you may overdo a little sometimes leaving the edge with a thick outline. Since we don't have control over the flow of the brush passing it a single time is not enough to fully select around the edges, leaving those "glows" around. To prevent those halos from appearing use a larger brush (200px or bigger) and pass a few times around the edges/boundaries without letting the cross in the centre of the brush approach too much to the edge - make sure Edge Aware is ticked. (Ignore the adjustment layers created and deleted, I was playing around to see what produced the best result )Ģ018_09_13_6964_AP_trial_copy photo.afphoto afphoto file with history so you can pan back through my document to see this in action. With the main background image at the bottom of the stack, I set both the ground layer and sky layer to Multiply blend mode, changing the opacity of the ground layer to 50%, producing the following result: I then inverted the selection and repeated the duplication, so I have 3 pixel layers total, the main image, a sky layer and a land layer. I used the smart selection brush to select the sky area, then duplicated this pixel area. This still created some white haloing, and I much prefer the workflow in the Photo Persona for this style of editing. I've created the following using the overlay paint tool in the Develop Persona, set to 100% hardness with edge detection on and then dropping the exposure level of the sky area painted. Is there a way to avoid creating the white edge in the first place (particularly for the Overlay Paint tool which I'd use a lot), or a better way to remove it than layers and blend options? The nearest I've come to fixing this one is by editing the (land) layer blend options - this seems to work up to a point but still doesn't quite eliminate all of the edge. In the second I used Photo Persona and followed one of the AP video tutorials to create an alpha channel selection (with refine) which I then applied to a Brightness and Contrast adjustment layer (for the land) and inverted to a Curves adjustment layer (for the sky). (Ignore the blotchy uneveness of the paint tool - that's another matter which I'll address separately!) When I painted in the overlay exposure adjustment I got a white edge on the overlay and was unable to find a way to remove it. In the first instance I used Develop Persona and the Overlay Paint tool to select the sky with edge aware. The original is a RAW (.NEF) image selected purely as a sample for testing. I'm now learning AP (v1.6.5.135), and right now trying to get the hang of the overlay and selection methods - but I'm getting the white edges shown in the attached screenshots. Until recently I've used mainly Nikon Capture NX2 and DxO for RAW processing - both have 'colour control point' tech to select areas for adjustments.
